Description

Technical Field

[0001] The utility model relates to the technical field of single piston rod cylinders, in particular to a double-acting single piston rod cylinder with a protective structure. Background Art

[0002] Double-acting single piston rod cylinder is an important actuator in industrial automation and mechanical transmission systems. It is widely used in various mechanical equipment to complete linear reciprocating motion and force transmission. Double-acting single piston rod cylinder realizes bidirectional motion of the piston rod by air intake at both ends, so it can be flexibly used in different working environments. Due to its simple structure, convenient control and low cost, double-acting single piston rod cylinder has been widely used in the field of modern industrial manufacturing.

[0003] However, in actual application, the traditional double-acting single-piston rod cylinder has some problems. On the one hand, the piston rod is exposed to the external environment and is easily invaded by pollutants such as dust, particles, and oil, which causes surface wear, thereby affecting the service life and working performance of the cylinder. On the other hand, the piston rod is easily disturbed and impacted by external forces during the telescopic movement, which may cause the cylinder to malfunction or be damaged. In order to improve the working reliability and service life of the cylinder, some cylinder designs with protective structures have appeared in the prior art. These protective structures usually protect the piston rod from the external environment by adding components such as protective sleeves and protective covers.

[0004] The existing double-acting single-piston rod cylinder protection structure still has some shortcomings in practical applications. First, the existing protective sleeve structure is often simple in design and cannot achieve flexible telescopic adjustment, resulting in poor adaptability of the cylinder under different working conditions. Secondly, although some protective structures can provide certain protection functions, they are relatively complicated during installation and operation, which increases the burden on users. In addition, while providing protection, the existing protective structure may affect the normal telescopic movement of the cylinder and reduce the working efficiency of the equipment. Therefore, we provide a double-acting single-piston rod cylinder with a protective structure. Utility Model Content
